The object of my invention is to keep the air in refrigerators perfectly free from any noxious gases which may arise from the chemical changes vwhich are continually taking place where animal products are stored in airtight apartments, especiallyin places Where said products are in a naked or unprotected 'condition from the closed air around them,

and in orderto accomplish this I take' ad vantage'of the law that thc use of charcoal held in space by wire screening, thereby exposing its'surface and the inclosing casing, will effectively and completely condense and neutralize any gases generated yother than the pure air, on which said charcoal .has no edect, l

it being also known that While the charcoal condeuses and neutralizes any effets matter which may be given off it is not in the least affected therefrom. To make this charcoal more effective and permanent Vin its usefulness, the exterio'rwall thereof should be continually in contact with' non-polluted or common air from the outside. in this Way'the charcoal will keep good for years, during which period the car,lhouse, or apartment in which the same is located `is kept healthy and sweet and al'so'the products stored therein,

and, furthermore,the charcoal will have no tendency to raise the temperature of the storage-space. This system of refrigeration will keep therein meats from getting sour or musty and will also keep fruits and vegetables from mildew or rot.

My invention is also practical for brewers use where changes are continually taking place duringthe fermentation of beer, certain chemical changes also taking place Where the Y beer isstored in open vats, and by theA use of' my invention the beer Willbe surrounded-at all times by perfectly pure air, thereby securther apparent that the employmentof vmy ining a practically perfect product, it being furvention in this connection will also prevent the use of sulfur or other means which are nonr utilized for the vpurpose of lneutralizing `bad odors.

-To the above ends the object sought to be obtained by the present invention is accomplished in vthe first place bythe action of the charcoal in keeping the storage dry, and in the next place the action of the charcoal is so 6o instantaneous in yneutralizing noxious gases that it does not allow the accumulation of effete matter or odors whichY otherwise would intensify and hasten the decomposition or chemical changes in the material stored Within its reach, since it will be easily seen that the material stored within a given space and the air within that space -being kept in a healthy and natural condition will have a -positive effect in keeping the lgoods therein in 7o a healthy condition, and the desired temperature will remain unchanged. The decomposition must be checked. by the action of the charcoal, as in all cases where air and Water are confined and deprived of their natural liberty they become destructive elements, and there is no other means of storing air and keeping. it in a healthy condition other than the means embodied in my invention as described.

' My invention also consist-s in providing an inlet and outlet for pure airv adjacent the eX- terior surface of the charcoal, whereby the latter is kept in a healthycondition.

. It further consist-s 'of novel details of con- 85 struction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure l represents a side elevation of a ventilator and air-purifier embodying my in- 9o vention. Fig. 2 represents a side elevation .ofthe interior thereof on an enlarged scale. Fig. 3 represents a vertical section on line fr, Fig. l, on an enlarged scale.

Similar letters of reference indicate corre- 95 spending parts in the figures.

vReferring to the drawings, A designates a boxer casing which is adapted` Ytob'e secured tothe side or other proper portion ofan apartment or car and has Within'the same the Adi-a-v Ico phragms Reformed of ganze, netting, lattice- Work, or foraminons plates and containing bej means of the nozzles or pipes E and Gr.r

In the casingback of the diaphragms are the deflectors F, which are of the form of slats or bars placed at an inclination and separated from each other, so as to leave air-passages between them.

The air passes upwardly through the nozzles G and so fills the chamber D, after which it continues upwardly and outwardly through the nozzles E, it being noted that by this construction a body of pure air adjacent the exterior surface of the charcoal is always provided, whereby the air within the compartment, car, or other device to which the purifier is attached is relieved of the noxious gases therein by means of the charcoal in proximity thereto, While said charcoal is kept in a perfect condition by reason of the proximity of the pure air, the manner of supplying the same and the inlets and outlets therefor being understood from Fig. 3. The special function of the defiectors or slats F is to serve as a protection to the innerorleft-hand screen B, (seen in Fig. 3,) and, if desired, said slats can be omitted, as can also the outer wall of the box or casing A. dent that my invention is applicable to both stationary and moving objects, and the box or casing A can be secured in position in any desired or convenient manner.

When. the device is attached to a car, as shown in the present instance, it will be evident that the inlet-nozzles G may be adjusted, if desired, so as to cause an ingress of the air by reason of the motion or progression of the car, While the egress of the air from the chamber D may be facilitated by turning the outlet-nozzles E in such a direction that the motion of the car assists or tends to form a vacuum in the chamber D.

In practice I employ a plurality of wire screens on each side of the charcoal, the screen nearest said charcoal being of fine wire or mesh, as indicated at B, while the exterior wire screens B are of coarser wire or mesh in order to support and give strength to said line wire.

If desired, I can employ a plurality of devices, as above described-viz., a body of charcoal contained between a fine and coarse wire screen, the same being superimposed upon each other and held from displacement in any suitable manner.

It will be apparent that other slight changes may be made by those skilled in the'art, which may come Within the scope of my invention, and I therefore do not desire to be limited in every instance to the exact construction I have herein shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

It will be evi-` l. A In afventilator or air-purifier, a body of charcoal, screens between which said charcoal is supported, an air-chamber adjacent the exterior surface of said charcoal, the inner surface of the latter being adapted to be exposed to noxious gases, and outlets and inlets for the upper and lower portions of said air-chamber.

2. In a ventilator or air-purifier, a body of charcoal, upright screens between which said charcoal is supported, an upright air-chamber-adjacent the exterior surface of said charcoal, the inner surface of the latter being adapted to be exposed tonoxious gases, and outlets'and inlets'for the upper and lower portions of said air-chamber.

3. In a ventilator or air-purifier, a body of charcoal, upright screens on each side thereof, the screens adjacent said charcoal being of line mesh and the outer screens being of coarser mesh, an air-chamber adjacent the exterior surface'of said charcoal, and inlet and outlet pipes for said air-chamber.

4. In a ventilator or air-purifier, a body of charcoal, upright screens on each side thereof, the screens adjacent said charcoal being of line mesh and the outer screens being of coarser mesh, an air-chamber adjacent the exterior surface of said charcoal, inlet and Outlet pipes for said chamber, and defiectors located near the inner surfacey of said charcoal.

5. A casing having a pipe connected therewith, an air-receiving chamber in communication with said inlet, an outlet for said chamber, deflectors on the inner side of said casing, and foraminous diaphragms with purifying materialbetween ,them, said diaphragms being interposed between the airreceiving chamber and said deflectors.

6. A ventilator and an air-purifier consisting of a casing having an air-pipe connected therewith, an air-receiving chamber within the casing in communication with said pipe, an outlet for said chamber, foraminous diaphragms rearward of said chamber with charcoal between them, and deflectors on the inner side of said charcoal whereby atmospheric air is directed by said pipe into said airchamber, then passes therethrough and out said outlet, whereby a body of air is always located in proximity to the outer side of said purifying material, the inner side thereof being adapted to absorb and neutralize the noxious gases adjacent thereto.

7. A ventilator and an air-purier consisting of a casing, having an air-inlet connected therewith, an air-receiving chamber Within said casing in communication with said inlet, an outlet for said chamber, a body of charcoal in said casing, a screen of fine Wire on either side of said charcoal and screens of coarser wire adjacent said fine-wire screens.
